Hi,

I have a triple-display setup, 2x 2k monitors @ 100% DPI and and 1x 4k TV @ 120% DPI. All displays are in "extended" mode in windows display settings. I have different wallappers defined for each display in DF. I usually have the TV disconnected, and only connect it when I need it. When I connect the TV, the wallpapers correctly update and every display gets its expected wallpaper. However, since I updated to DF 11 beta version, when I disconnect the TV, the wallpapers do not update and half the wallpaper of the TV ends up on the monitors. I have to manually open DF and go to the wallpaper section and apply the wallpaper settings for the wallpapers to be corrected. The issue is 100% reproducible and did NOT exist in DF 10.x.

P.S. This might require a multi-DPI display setup to be reproducible.

Best regards

I started from all displays being connected, cleared the log and then enabled L1 logging, and then disconnected the TV and confirmed the wallpaper on the monitors got messed up as expected, and then exproted the file. The plain log files are attched; I excluded the html file since it seems to include a lot of system and user information. If the issue cannot be troubleshooted just by the log files, I can also include the html file.

I have attached the output.

By the way, to add one more observation, even when I connect the TV, I do see that the wallpapers gets messed up, but a wallpaper refresh happens in a few seconds and fixes the wallpapers. When the display is disconnected, however, this refresh never happens and the wallapapers remain messed up until I refresh them manually. The bug could simply be that the wallpapers are not refreshed in DF 11 when a display is disconnected, while they did in DF 10.

Just disabling in Display Settings.

I am not sure if slideshow is the best way to replicate this since it will force a refresh every time the wallpaper is supposed to change. The problem here is that every display change is supposed to force a wallpaper refresh, while the wallpaper never refreshes after the TV is disconnecetd. I have three static wallpapers defined, one for each display, and my TV has a different DPI than my monitors. The attached screenshots should help demonstrate the problem. '3-display.jpg' shows the wallpaperps when all three displays are connected. '2-display-broken.jpg' shows what happens when I disconnect the TV: the TV's wallpaper ends up spanning acorss the two monitors. '2-display-correct.jpg' shows what happens when I manually reapply the wallpapers in DF in this case, which forces the wallpapers to be refreshed and corrected.

By the way, the wallpaper on the TV is not actually static, it is a slideshow. The wallpaper on the two monitors, however, is static.

@owen Any luck replicating this issue?
